Because Windows has echo cancellation. I believe skype turns it on for you.You might be able to find something with a Google search. Use the search term Ubuntu instead of Linux Mint if you can't find anything

Not an expert here but you might want to lower down the sensitivity of microphone? Maybe it would make a difference. Type this command in the terminal and adjust the settings.
